Bees are altruistic: study

Scientists have found that even in the hopeless situation of colony collapse, queenless honeybees will still show remarkable altruism towards their colony, defending and feeding the collective.
Normally a honey bee colony contains a single reproductive queen attended by thousands of sterile workers, but no one had studied how the workers respond when the queen dies.
To address this gap, Dr Andrew Barron from Macquarie University in Australia observed the behavioural patterns of queenless honeybee colonies in collaboration with researchers at the University of Illinois.
"We've studied bees so intensely, but no-one's kept watching after the queen bee has died. Now for the first time, we can see that in a hopeless queenless colony - the terminal phase - honeybees continue to work together to defend the colony, forage and feed each other. Altruism persists, despite earlier assumptions to the contrary," said Barron.

The researchers were surprised to see this altruism in a failing colony. Without the queen the workers began laying eggs and raising male drones.
It was assumed that reproductive worker bees would selfishly prioritise their own reproduction over colony care - seeing an increase of selfish behaviour, and corresponding decrease in altruism.
"Although selfish behaviour did increase we saw that altruism did not decrease. The colonies effectively became worker communes - collective societies where bees became generalists, maintaining and defending the colony together, to the end," Barron said.
